The Rock Cycle Ultimate Trivia! Quiz
Looking for the ultimate rock cycle trivia quiz? Here is the one quiz for you. The three main types of rock are igneous rock, metamorphic rock, and sedimentary rock. These rocks differ from each other based on how they are formed and their characteristics when introduced to certain elements. By taking this quiz, you will get to refresh your memory on the types of rocks and processes they undergo.
- 1.
What are the 3 types of rocks involved in the rock cycle?
- A.
Sandstone, shale, basalt
- B.
Dactylic, iambic, spondaic
- C.
Igneous, sedimentary, metamorphic
Correct Answer
C. Igneous, sedimentary, metamorphicExplanation
The rock cycle involves the transformation of rocks from one type to another over time. Igneous rocks are formed from the solidification of molten material, sedimentary rocks are formed from the accumulation and compaction of sediments, and metamorphic rocks are formed from the alteration of existing rocks under high pressure and temperature. These three types of rocks represent the different stages and processes in the rock cycle.Rate this question:

What are igneous rocks made from?
- A.
Molten rock that has cooled
- B.
Pieces of other rocks that have collected and cemented together
- C.
Mountains that have weathered away
Correct Answer
A. Molten rock that has cooledExplanation
Igneous rocks are formed from molten rock that has cooled and solidified. When magma or lava cools, it undergoes a process called solidification, where it transforms from a liquid state to a solid state. As the molten rock cools, minerals crystallize and interlock, forming the igneous rock. This process can occur both beneath the Earth's surface, forming intrusive igneous rocks, or on the Earth's surface, forming extrusive igneous rocks. Therefore, the correct answer is "molten rock that has cooled."Rate this question:

Rocks are made ...
- A.
Only of organic substances that contain carbon
- B.
Always of quartz and silicon
- C.
Of one or more minerals
Correct Answer
C. Of one or more mineralsExplanation
Rocks are made of one or more minerals. This is because rocks are naturally occurring solid aggregates of minerals, which are inorganic substances. Minerals are the building blocks of rocks and can be composed of various elements and compounds. Therefore, rocks can consist of a single mineral or a combination of different minerals.Rate this question:

What are sedimentary rocks made of?
- A.
Molten rock that has cooled
- B.
Pieces of other rocks that have collected and cemented together
- C.
Petrified trees
Correct Answer
B. Pieces of other rocks that have collected and cemented togetherExplanation
Sedimentary rocks are formed from the accumulation and consolidation of sediments, which are small pieces of other rocks or minerals. Over time, these sediments are deposited and undergo processes such as compaction and cementation, where they are squeezed together and bound by minerals, creating a solid rock. This process can occur in various environments, such as rivers, oceans, or deserts, and is responsible for the formation of rocks like sandstone, limestone, and shale.Rate this question:
-
- 5.
Which of these is a sedimentary rock?
- A.
Granite
- B.
Pumice
- C.
Sandstone
Correct Answer
C. SandstoneExplanation
Sandstone is a sedimentary rock because it is formed from the accumulation and compaction of sediment particles, such as sand, over time. Sedimentary rocks are typically formed through processes like weathering, erosion, and deposition, where sediments are transported and eventually settle to form rock layers. Granite, on the other hand, is an igneous rock that forms from the cooling and solidification of molten magma, while pumice is a volcanic rock that is formed from the rapid cooling of lava with high gas content.Rate this question:

Which statement is TRUE about the rock cycle?
- A.
It involves heat, pressure and cooling
- B.
It stops after metamorphic rocks form
- C.
Weathering only occurs in igneous rocks
Correct Answer
A. It involves heat, pressure and coolingExplanation
The rock cycle involves various processes, including heat, pressure, and cooling. These factors play a crucial role in the formation and transformation of rocks. Heat and pressure can cause existing rocks to undergo metamorphism and change into metamorphic rocks. Cooling of molten rock leads to the formation of igneous rocks. Therefore, the statement "it involves heat, pressure, and cooling" accurately describes the rock cycle.Rate this question:

What happens to metamorphic rock when it is subjected to extreme heat?
- A.
It breaks apart into sediments
- B.
It forms igneous rocks
- C.
It melts into magma
Correct Answer
C. It melts into magmaExplanation
When metamorphic rock is subjected to extreme heat, it undergoes a process called melting. This means that the rock transitions from a solid state to a liquid state, forming magma. Magma is a molten mixture of various minerals and elements, and it can eventually cool and solidify to form igneous rocks. Therefore, the correct answer is that metamorphic rock melts into magma when exposed to extreme heat.Rate this question:

What kind of rock most often contains fossils?
- A.
Igneous
- B.
Sedimentary
- C.
Metamorphic
Correct Answer
B. SedimentaryExplanation
Sedimentary rock most often contains fossils because it is formed from layers of sediment that accumulate over time. Fossils are typically found in sedimentary rock because this type of rock is formed from the remains of plants and animals that have been preserved in the sediment. Igneous rock is formed from cooled lava or magma and does not typically contain fossils. Metamorphic rock is formed from the transformation of existing rock through heat and pressure, and it also does not typically contain fossils.Rate this question:

- 9.
Which of the following is a metamorphic rock?
- A.
Marble
- B.
Shale
- C.
Basalt
Correct Answer
A. MarbleExplanation
Marble is a metamorphic rock because it is formed from the recrystallization of limestone under high temperature and pressure. This process causes the minerals in the limestone to rearrange and form new crystals, resulting in the formation of marble. Shale, on the other hand, is a sedimentary rock, and basalt is an igneous rock.Rate this question:

Which of the following is an igneous rock?
- A.
Graphite
- B.
Limestone
- C.
Quartzite
Correct Answer
A. GraphiteExplanation
Graphite is an igneous rock because it is formed from the cooling and solidification of magma or lava. Igneous rocks are created through the process of crystallization, where molten material cools and hardens, forming solid rock. Graphite, which is composed of carbon, is formed under high temperatures and pressures deep within the Earth's crust. It undergoes metamorphism, transforming from its original form of coal to graphite. Therefore, graphite is classified as an igneous rock.Rate this question:
